@RAMPAGE
Firstly. Thanks for the tag.
Secondly. Wow! A difficult topic. I guess you, yourself, are a writer/columnist?
Thirdly, answering you sequentially:
a. Any particular part of the day or night can not be identified by me, as an individual, where I may or may not feel particularly creative. My profession has either enhanced or ingrained that adaptability and dexterity. Although, I do admit, that had a predilection to write as a school kid, and as a professional, have written some Public Relation stuff for one of the biggest organisations in India, albeit, incognito. So, here, I do share similarity with
@Joe Shearer, perhaps.
b. Brainstorming, again I would agree that I too, do not indulge in any such act. On the contrary, any activity requiring a brainstorm session or a conference is a strict no for me. Maybe has to do with a lower threshold for tolerating idiocy? However, in my defence, am a 'lone wolf'. Prefer to work on my own with minimal interference, or a contributive team.
c. For space, it is anywhere. Although, I prefer a neat table to myself for my work.
d. No. What I write, would not be a reflection of my personal life. Although, perspectives do get conveyed as that is subconscious.
What of you? It shall be interesting to note your answers. (You have give a summation)
Thanks
